Title: libvirt_vm: remove setup_serial_ports() method.

Commit c37a86ca picked out the create_serial_console() from setup_serial_ports(),
and call it in env_process(). But it is not robust enough.

This patch rename the setup_serial_ports() to create_serial_console() to be called
in env_process() and remove the older create_serial_console().
